To all whom it may concern:

Be it known that T, Faun D. SUMNER, a citizen of the United States, residing at Danville, in the county of Vermilion and State of Illinois, have invented certain new and useful Improvements in Heating and Ventilating Casings for Radiators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which .it appe rtains to make and use the same.

My invention has for one object to provide means for directing fresh air to the lower part of a radiator and confining it to some extent around the latter, whereby it will be effectively heated, and a further object is to provide simple means whereby the supply of fresh air may be cut d, other means being provided whereby the air with in the room is allowed access to the radiator when the fresh air supply is checked.

With the foregoing general object in view, the invention resides in certain novel features of construction and in unique combinations of parts to be hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying drawings which constitute a part of this application and in which:

Figure l is an end elevation of a radiator and a vertical transverse section of the invention applied thereto;

Fig. 2 is a vertical longitudinal section on the plane of the line 2'-2 of Fig. 1;

Fig. 3 is a horizontal section on the plane of the line 33 of Fig. 1;

til

Fig. a is a perspective view showing more particularly the valve operating means;

Fig. 5 is. a perspective of a part of the lower section of the radiator casing;

Fig. 6 is a similar view of apart of the upper casing section;

Fig. 7 is a front elevation showing more particularly the indicator.

In the drawings above briefly described, the numeral 1 has reference to a sheet metal casing formed of alower section 2 and an upper section 3, said casing bein shaped to totally surround and extend a s ight distance above a radiator R. The lower sec tion 2 is formed of front and rear sheet metal plates at and 5 respectively whose ends are bent laterally at b to form and walls for P said section, said ends e being joined by suitable scams. 7 and having their abutting edges notched at 8 to form openings through which the pipes P of the radiator R extend. The body portions of the plates f and 5 are formed respectively with horizontally elongated air inlets 9 and 10, the former communicating with the room in which the radiator is located while the opening 10 registers with a passage member 11 which extends through the Wall W of the building to supply fresh air to the interior thereof.

The plates 4 and 5 have their upper edges bent outwardly, inwardly and then upwardly to simultaneously form horizontal ledges l2 and vertical flanges 13 rising from the inner edges thereof, said ledges 12 receiving thereon outwardly bent flanges 147 on the lower edge of the front and rear sides of the upper casing section 3, this section being formed similarly to section 2, having however no openings such as 9 and 10. The

ends of the section 3 are preferably received in channels 15 on horizontal 'sheet metal "strips 16 which are secured to the upper edges of the ends of the section 2 as shown in Figs. 2 and 5. The upper edges of the section 3 are preferably bent outwardly to form reinforcing flanges 17 .and the por tions of these flanges at the corners of the casing are reinforced by angular metal plates 18, (Fig. 6). Other plates 19 are secured to the under sides of the flanges 17 at the upper ends of the seams 20 which con nect the front and rear halves of section 3.

Vertically disposed channel-shaped 1 ide tracks 21 are rigidly secured to the ower section 2 along the ends of the o enings 9 and 10, said tracks extending above said section '2 as shown in Figs. 1 and 2 and being secured by bolts or the like 22 to the upper section 3, whereby the latter is rigidly secured in place. Damper lates 23 ar disposed within the casing an the ends o said plates are received sli ably in the channels of the tracks 21, said plates being suspended by means of chains 2% from crank armsv 25 which extend on opposite sides of the axis of a horizontal rock shaft 26. Shaft 26 extends transversely across the casing above the radiator and is mounted in suitable bean ings, being equipped on its front end with a suitable operating handle 27.

The chains 24f preferably pass over pulleys 28 secured to the front and rear sides or the casing section 3 and are adjustably hooks or the like 29 engaging longitudinally spaced openings 30 in said arms. This latter arrangement is preferable in order that the damper plates 23 may be adjusted to open the required amount. When the device is set up, the chains 24 are of the proper length to insure that when one dam per plate 23 is closed the other is opened to the proper extent, this extent being controlled by means of the hooks 29 and open ings 30 as described. By this arrangement, it will be obvious that when the shaft 26 is turned in the proper direction, the open damper plate will be closed whereas the other will simultaneously be opened. The passage of air through the openings 9 and 10 may thus be controlled by means of the single handle 27.

The front chain 24 carries a forwardly projecting pointer 31 received in a vertical slot 32 in an indicating plate 33, the latter being secured to the front of the casing section 3. On one-half of the plate 33 the words Back damper are positioned and at the upper and lower ends of this half appear the words Closed and Opened respectively, while the other half of plate 33 relates to the front damper and the words Open and Closed appear respectively at the upper and lower ends of this half. It will thus be evident that as the handle 27 is operated to move the chains 24, the,

I as shown in the drawings, fresh air may be admitted into the casing to. be heated by the radiator before being expelled into the room or by closing the rear damper and opening the front, the air within the room may be set in continual circulation by the radiator. The device therefore acts not only to confine the air around the radiator while it is being heated but also serves to a large extent as a ventilator.

From the foregoing taken in connection with the accompanying drawings, the construction, manner of operation and advantages of the improved apparatus will be understood and it will be observed that although comparatively simple and inexpensive construction has been employed, the invention will be highly eflicient. For these reasons, the construction in question constitutes the preferred form of the device but it is to be understood that within the scope of the invention as claimed, numerous changes may be made without sacrificing the principal advantages.

I claim:

1. In an air circulating device, the combination of a casing shaped to surround a radiator, said casing having air inlets in its opposite sides and located adjacent its lower end, and vertical guides along the edges of said openings, a pair of vertically sliding damper lates mounted in said guides, a rock shaft extending transversely across the upper end of the casing and having an operating knob at the front of the latter, crank arms extendingin opposite directions from the opposite ends of said rock shaft and positioned adjacent the front and rear sides of the casing and on the interior of the latter, and suspending members depending from said arms and connected with said damper plates.

2. The combination of a casing shaped to surround a radiator and having in its front and rear sides a pair of air inlet openings located adjacent the lower ends of said sides, the front side of said casing having a vertical slot spaced above its air inlet opening, and vertical guides along the edges of said openings, a pair of vertically moving damper plates slidably mounted in said guides, a transverse rock shaft extending across the upper end of the casing and having an operatingknob positioned at the front of the latter, oppositely extending crank arms carried by the opposite ends of said rock shaft and positioned within the casing, suspending members depending from said crank arms and connected with said damper plates, a pointer secured to one of said suspending members and received slidably in the aforesaid slot, and indicating means adjacent said slot for cooperation with said pointer to disclose the positions of the damper plates.

3. A device of the class described comprising a casing shaped to surround a radiatorand formed of upper and lower sections, the front and rear sides of the lower section having air inlet openings, channelshaped vertical tracks rigidly secured to the inner faces of said front and rear sides adj acentthe ends of said openings, said tracks extending above the lower section, means rigidly securing the upper ends of said tracks to the upper section of the casing, and front and rear damper plates slidable vertically in the channels of said tracks.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
